Insulating rain noise from roofing systems is particularly important in buildings with large spans, as the greater distance between supports leads to less rigidity of the systems. This work aims analyze the influence of damping layers on the acoustic performance of covering systems with metallic tiles during the action of artificial rain produced in a laboratory environment. The tests were carried out according to the parameters of ISO 10140, Parts 1, 3 and 5, in 12 different compositions of roofing systems. For comparison purposes, 4 types of simple tiles were also tested. The results show that, in multilayer
systems, filling with glass wool between two tiles is the most efficient, with results of LIA = 74 dB for the simple trapezoidal tile TP-30 and LIA = 52 dB for the system with glass wool and elastomeric tape.
